Gleeks, here’s something you already know: Ricky Martin is hot like fire. You’ve probably already seen his performance of LMFAO’s “Sexy and I Know It” and he’s even steamier on next week’s episode of Glee, titled “The Spanish Teacher.” EW got an early peek at the episode, in which Martin plays David Martinez, a night school Spanish teacher who helps Will (Matthew Morrison) when a student complains about his teaching abilities. But that’s only one part of a pretty plot-packed hour of Glee. Here are the highlights [MILD SPOILER ALERTS]…

Will and Sue battle it out over getting tenure at McKinley

Sue announces that she wants to have a baby by artificial insemination (“With whose vagina?” is asked at least twice in the episode)

NeNe Leakes returns as Roz Washington and takes a stab at choreographing the Cheerios. She also has an EPIC verbal takedown with Sue. Example: “Start praying you give birth to a child who likes to eat sand because that’s all that’s coming out of those old wrinkly boobs.”
